I have had one runner *on my second tribe, he's in his 40's* but I wish I could have more. It's funny, the few times I have a runner, you never realize it until you see them buzzing around the screen after 14.. before that, they all run about the same as kids (unless it's one who hates running.. I swear, those are the ones that annoy me!)

But I've also had a few women who were not runners, but they ran as fast as a runner whenever they wanted to, um, improve their 'parenting' skills! But put them to anything else, and they were just as slow as everyone else.
